CHEM 210 Biochemistry Module 1 to 8 Exams' & Final Exam (2025 / 2026) Portage Learning Questions and Verified Answers, 100% Guarantee Pas 1. What do Biochemists study? >>> 1. The relationship between structure and func- tion of biomolecules 2. Chemical reactions of organisms 3. Communication within and among organisms 2. Smaller elements are favored because they can form stable covalent bonds. T or F >>> True. Strong bonds form by significant overlap of atoms, such as carbon and hydrogen, allowing them to share electrons. 3. What is the bond angle of a Linear molecule? >>> 180 degrees 4. What is the bond angle of a Trigonal Planar? >>> 120 degrees 5. What is the bond angle of a Trigonal Pyramidal? >>> 107.5 degrees 6. what is the bond angle of Tetrahedral? >>> 109.5 degrees 7. What is carbon referred to in the chemical world? >>> The superglue 8. What does organic chemistry study? >>> Focuses on the chemical and physical properties of carbon compounds 9. What does inorganic chemistry study? >>> The field dealing with metals, minerals, and other non-organic compounds 10. How many bonds can a Carbon form? >>> 4! Due to having 4 valence electrons 11. What is a long chain of carbons called? >>> Polymers 12. What is a cyclic compound? >>> Carbons joined together in a closed chain 13. What are carbon compounds called? >>> Alkanes 14. Condensed structures give a better idea of a molecules structure, com- pared to chemical formula. T or F >>> T 15. Structural formula gives an even better idea of a molecules structure, compared to chemical formula >>> T 16. Advantage of cyclic carbon compounds >>> They are more restricted in their movements and orientation - advantageous for building structures and maintaining shape 17. Carbon can form double and triple bonds with other carbon atoms or atoms of other elements. T or F >>> T 18. Line-bond Drawing >>> Most efficient method to show structure, but requires the most interpretation. 19. Functional group >>> specific arrangement of atoms; they define the chemistry of the molecule and control the properties of the compound. 20. What dictates the chemical and physical properties of compounds, includ- ing biochemical compounds? >>> The structure 21. Biomolecules >>> Molecules that are part of the cell or molecules that are excreted by cells. 22. Macromolecules >>> large biomolecules 23. Molecular mass of a Macromolecule >>> 5,000 g/mol or greater 24. What are daltons used for? >>> Larger molecules use Daltons for mass. 1 Da = 1 g/mol 25. Larger molecules develop more complex structures. T or F >>> T 26. What is 25,000 Da in Kilodaltons >>> 25 kDa 27. Monomers >>> Single, smallest building block used to build macromolecules. 28. What is the monomer of DNA? Of proteins? Of carbohydrates? >>> Nucleotide; Amino Acids; Sugar molecule 29. Supramolecular Complexes >>> A complex of two or more macromolecules that routinely interact to function in the cell 30. What is the purpose of a supramolecular complex? >>> The macromolecules retain individual units but stick to one another for a time to accomplish a task and then often break apart once the job is done. 31. All cells are defined by a >>> Plasma membrane (or cellular membrane) 32. What is the plasma membrane made of? >>> Lipids and non-polar proteins, making it impermeable to water, ions, and large molecules. 33. Prokaryotes vs. Eukaryotes >>> Prokaryotes include bacteria and other single celled organisms. Eukaryotes are the larger multicellular organisms that include algae, fungi, plants, and animals.
